Javanaria View in CoL gen. nov.

Type species: Javanaria gracilipes View in CoL sp. nov.

Etymology: The generic name is a combination of two words: “ Java ”, the “terra typica”, and a part of the generic name Nasoonaria . Males of Nasoonaria , like males of the type species of the new genus, have an extremely developed distal suprategular apophysis. The gender of the new name is feminine.

Diagnosis: The genus contains large-sized erigonines with relatively long and slender legs, with a total length of 2.2-2.3, which are characterized by the following combination of somatic and genitalic characters:

1) Carapace slightly modified, eyes somewhat enlarged, cephalic pits (= sulci) absent ( Figs 5-6 View Figs 1-9 ).

2) Abdomen with a dorsal pattern ( Fig. 5 View Figs 1-9 ).

3) Legs relatively long and slender.

4) Chaetotaxy formula; each metatarsus with a trichobothrium; TmI 0.52-0.60.

5) Palpal tibia unmodified.

6) Paracymbium long and narrow ( Fig. 15 View Figs 15-20 ).

7) Median membrane strongly reduced.

8) Distal suprategular apophysis extremely developed, massive ( Figs 15, 18 View Figs 15-20 ).

9) Radix strongly reduced, embolus relatively wide, flat, convector absent ( Figs 19-20 View Figs 15-20 ).

Species included: Only the type species, Javanaria gracilipes sp. nov.

Taxonomic remarks: In its large size and long legs J. gracilipes sp. nov. resembles some taxa of the subfamilies Linyphiinae and Micronetinae , but its palpal conformation is of the classically erigonine-type. The palp of J. gracilipes sp. nov. somewhat resembles that of Nasoonaria . However, this similarity is superficial, mainly due to the large distal suprategular apophysis. Today its is impossible to find a genus among the known erigonines to which Javanaria gen. nov. appears to be close. Most likely the closest relatives will be found among taxa not yet described.

Distribution: Known only from the type locality on Java, Indonesia.
